As far as I can tell, this simple example below should be working but it doesn't. I'm obviously missing something, but I can't for the life of me figure it out.
The first .field div should have red text, but it simply does not...
Running Chrome browser on Mac.
http://codepen.io/anon/pen/obbmjd
p .field:first-child {
color: red;
}
<p>
<div class="field">first - should be red</div>
<div class="field">second</div>
</p>
The HTML is invalid.
A p element can't contain a div element. This results in the following:
<p></p>
<div class="field">first - should be red</div>
<div class="field">second</div>
<p></p>
As you can see, the browser is automatically closing the p tags, which explains why your selector isn't matching anything.
If the HTML was actually valid, then your selector would work. For instance, if you replace the div elements with span elements, the following would work:
Updated Example
p .field:first-child {
color: #f00;
}
try
.field:first-child {
color: red;
}

I need change a color for this element
<div class="box download">
<div class="box-inner-block">
Plugin Windows
</div>
</div>
I call a from CSS with:
.download.box-inner-block a {
color: white!important;
}
But it does not work, why? I need this color only for the element in .box-inner-block inside .download.
Is this what you are looking for as understood in your question ?
If so you need to carefully watch how you indent and construct your css.
As you can see in my snippet I added a space between:
.download .box-inner-block a
in order to make that work.
You can also remove !important from you css as it will not be useful in that case. If you need it, don't forget to add a space bewtween white and !important
.download {
background-color: black;
}
.download .box-inner-block a {
color: white;
}
<div class="box download">
<div class="box-inner-block">
Plugin Windows
</div>
</div>
You are using the wrong selector, as .download.box-inner-block selects elements which has both download AND box-inner-block classes.
<div class="download box-inner-block"/>
To target nested elements, leave a space between the two class selectors. So the correct selector in your case is:
.download .box-inner-block a {
color: white;
}
In this case you can drop !important too.
<div class="wrapper">
<!--
Several random elements that I'm not able to predict.
div, p, h3, etc.
-->
<div class="foo">...</div>
<!--
Could have only 1 .foo, 2 .foo, or 3, 4, 5 .foo...
-->
<div class="foo">...</div>
<!--
Also several random elements
-->
</div>
HTML code is something like above. Now I know the reason why div.foo:first-of-type doesn't work. But is there any alternative solution?
How can I select the first .foo? How can I select the last .foo? Of course via pure css...
Thanks!
How can I select the first .foo?
The technique described here: CSS selector for first element with class:
div.foo {
/* Style all */
}
div.foo ~ div.foo {
/* Revert styles for all but the first */
}
How can I select the last .foo?
The technique described above relies on sibling selectors and overrides. The biggest limitation of sibling selectors is that they only work in one direction, and since they work for the first element by overriding for all elements after the first, they won't work for the last because you can't select siblings that come before some other element using sibling selectors.
There is no pure CSS alternative.
Any HTML5 browser will let you use nth-of-type as it is intended...
I am not saying this is a recomended technique, I am just showing how this option works ...
I don't know if you will like it or not, but AFAIK is the only way to get what you want for the last one (as BoltClock says)
foo:first-of-type {
background-color: lightgreen;
}
foo:last-of-type {
background-color: lightblue;
}
<div>
<div>div</div>
<foo>foo</foo>
<div>div</div>
<foo>foo</foo>
<div>div</div>
<foo>foo</foo>
</div>
you can use first-child, and last-child
html
<div class="wrapper">
<p>1</p>
<p>2</p>
<p>3</p>
</div>
css
p:first-child {
color: red;
}
p:last-child {
color: green;
}
Here's a JsFiddle Example
Beware that last-child is only supported since IE 9, and first-child is supported from IE 7
I want to disable text selection for specific elements. For example:
p {
-moz-user-select: none
}
span {
-moz-user-select: text
}
<div>
<p>first paragraph</p>
<span>first span</span>
<p>second paragraph</p>
<span>second span</span>
</div>
The first and second paragraph cannot be selected individually. However, if I select the first span and drag down to select the second span, the second paragraph will become selected in the process. I'd like to prevent this (it functions as expected in WebKit).
I'm using Firefox 14.0.1. JSFiddle for reference: http://jsfiddle.net/GFNDY/
Since the selection only "apparently" includes the <p>s (for instance if you copy, only the non-<p> tags are saved in the clipboard), then all you need to do is make sure the browser doesn't color it; that can be done by overriding the default selection-style using the CSS ::selection specifier (::-moz-selection for Mozilla).
So the CSS will have something like:
p::-moz-selection {
background: transparent;
color: #000000;
}
Here's a modified version of your demo that behaves as expected: Link.Hope that helped you in any manner!
I'm using the following code to add separators between my menu items:
#navigation_center li:before {
content: "| ";
color: #fff;
}
Now I want the first item not to have a separator in front of it, so I figured out the following code:
#navigation_center li:before:first-child {
content: none;
}
but that's not doing anything. Is it possible to combine :before and :first-child?
Try
#navigation_center li:first-child:before {
content: '';
}
Edit: I wanted to expand on this answer with comments made by FelipeAls. The original question used :first which is not a valid CSS selector. Instead, use :first-child. Also the order of the pseudo-selectors is important. The first child selector must come first.
I tend to think of :before as a kind of modifier to a selector. It does not actually select an element only the space just before the selected element.
Although hradac's answer should do the trick i thought it would be best to run through some possible permutations to help newcommers.
.works:first-child:before
{
color: green;
content: 'working ';
}
.works:not(:first-child):after
{
color: green;
content: ' is working';
}
.broken:before:first-child
{
color: red;
content: 'this will never show up';
}
.broken:after:not(:first-child)
{
color: red;
content: 'and this will not show up either';
}
works:
<div>
<div class='works'>
something
</div>
<div class='works'>
something
</div>
<div class='works'>
something
</div>
</div>
<hr/>
broken:
<div>
<div class='broken'>
something
</div>
<div class='broken'>
something
</div>
<div class='broken'>
something
</div>
</div>
Let's take this apart:
Three div.works are inside a div
Three div.broken are also inside a div
The first rule of CSS adds a green text "working " before. It does so by selecting the first-child and then selecting the empty space right before it.
The second rule adds " is working" after each block that comes after first, by analogy it first selects each block that doesn't fall under the first-child definition, and then selects the empty space before them.
The following two rules, will not find a block to attach themselves to. The :before:first-child attempts to select an empty space, but then tests if it is a first-child and it is not (since technically it's not yet in the DOM tree), the similar problem is with :not(:first-child).
I have a row of divs with :hover and it is working when I hover over the images within the divs. However, it doesn't want to work for the text. I am on the newer side of html and css, so help appreciated. I must be missing something obvious?
The first one with the div.topIconsHover:hover CSS works. The other does not. I have tried applying the topIconsHover class to the div as well and it still doesn't work. So, I must be doing something wrong with the HTML? But I'm just not sure what. Help appreciated! Thanks.
Note: I have the CSS in an external sheet.
div.topIconsHover:hover {
background-color:#555555;
}
<div class="topIcons topIconsHover">
<img src="tools16lg.png" />
</div>
div.topTextHover:hover {
background-color:#555555;
color:#ffffff
}
<div id="topBrowse" class="topTextHover">
Browse
</div>
The color attribute is working only with text elements, not divs. So you should apply the class tag to your href tag like this :
<style type="text/css">
.topTextHover:hover {
background-color:#555555;
color:#ffffff
}
</style>
<div id="topBrowse">
Browse
</div>
EDIT :
If you're looking to define a base class for the link itself, and a HOVER state, do it like this :
<style type="text/css">
.topTextHover {
background-color: transparent;
color: #0000ff;
}
.topTextHover:hover {
background-color: #555555;
color: #ffffff;
}
</style>
<div id="topBrowse">
Browse
</div>
Good luck
You applied style to the ":hover text" but not for links. This should do the trick (not tested):
div.topIconsHover:hover {
background-color:#555555;
}
<div class="topIcons topIconsHover">
<img src="tools16lg.png" />
</div>
div.topTextHover:hover, div.topTextHover:hover a {
background-color:#555555;
color:#ffffff
}
<div id="topBrowse" class="topTextHover">
Browse
</div>
Anchor tags have a default text colour which gets priority (usually blue). What you need is to define this explicitly:
div.topIconsHover:hover {
background-color: #555555;
}
div.topTextHover:hover {
background-color: #555555;
}
div.topTextHover:hover a {
color: #ffffff
}
There are two really simple ways to resolve this issue.
First if you don't have any height/width requirements on the anchor tag (<a href=''></a>) being inside the div do the following:
.topTextHover a:hover{
background-color:#555555;
color:#ffffff
}
<div id="topBrowse" class="topTextHover">
Browse
</div>
If you do have spacial requirements for the text inside the div (i.e. you want the text to be vertically-aligned to the center and horizontally centered) then I would do the following note* this is backwards compatible but is really only compliant with CSS3
#BrowseLink:hover {
background-color:#555555;
color:#ffffff
}
<a id="BrowseLink" href="browse.html">
<div id="topBrowse" class="topTextHover">
Browse
</div>
</a>
Also of note IE6 doesn't like the pseudo-class hover on anything other than an anchor tag and therefor will not work properly. This may be applicable in other browsers as well but the main one that I know that has issues is IE6 of the browsers that are typically seen on a website.
